Gt911 Register Map Extra Quality – Working

The GT911 register space is divided into functional blocks for commands, configuration, and coordinate reporting. STMicroelectronics Community GOODiX GT911 Programming Guide 2014-08-04_Rev.00

The starting point for the first touch. Data is usually formatted as: Programming Flow Initialize I2C: Set the speed (standard 100kHz or fast 400kHz). Configuration: (Optional) Write parameters to if you need to change the screen resolution or orientation. Polling Loop: Read register Check if Bit 7 is high. gt911 register map

// Read the first touch point (7 bytes) uint8_t raw[35]; // Space for up to 5 touches * 7 bytes i2c_read_bytes(GT911_ADDR, GT911_TOUCH1, raw, touch_count * 7); The GT911 register space is divided into functional

Let’s pull back the curtain and map out the GT911’s internal memory. touch_count * 7)
